Abstract
208,968. Golby, F. W., (Lewis Felling Machine Co.). April 5, 1923. Sewing - machines; feed by devices engaging the upper surface of work. - An upperfeed device for co-operating with an underfeed dog is mounted on the usual presser bar and actuated by the engagement of a stud on the needle bar with an actuating lever acting through a cam and levers to give the work-engaging and feed movements. The fitting is attached to the presser-bar 13 by a screw 36 and comprises a frame 20 carrying at its lower end a foot with a recess for the feed-dog 22 and at its upper part supporting a stud 38 on which is mounted the actuating lever 19 engaging a stud 17 on the needle-bar. A cam 26, adjustably secured to the lever 19 by a screw 43 entering a slot, engages a lever 24 pivoted at 46 and carrying the dog 22 to which it transmits feed-movement. A roller 50 on the cam also engages a cam-shaped extension of a lever 25 also pivoted at 46 and bearing on the top of the dog to which it gives workengaging movement. The dog is partly supported and its return movements are effected by a spring 23. The cam 26 is so shaped and placed with reference to the levers that by its adjustment the feed stroke of the dog 22 may be varied in accordance with that of the under dog 15.
